Four months ago, a mucus sample arrived in Dr. Ali Mohamed Zaki’s laboratory in Saudi Arabia.
The mucus had been coughed up by a 60-year-old Saudi Arabian man with a strange case of pneumonia. He had been admitted to the Dr. Soliman Fakeeh hospital in Jeddah on June 13; soon after, his kidney... Read More
Measles vaccine given with painless and easy-to-administer microneedle patches can immunize against measles at least as well as vaccine given with conventional hypodermic needles, according to research done by the Georgia Institute of Technology and the Centers for Disease Control and Prevention...

Vincent and Dickson discuss the exchange of messenger RNAs between a parasitic plant and its hosts.
The United States has reported the first known death caused by the H3N2 variant virus, the new swine flu that has been jumping from pigs to people there.
And in another development that underscores how dynamic the intersection is between pigs, people and influenza viruses, health authorities in... Read More
Study shows that key proteins in mucus prevent bacterial adhesion to surfaces, could help prevent growth of biofilms.
Slimy layers of bacterial growth, known as biofilms, pose a significant hazard in industrial and medical settings. Once established, biofilms are very difficult to remove, and... Read More
In a study that's already being greeted with notes of caution, Danish researchers report that children whose mothers had the flu or ran a fever lasting more than a week during pregnancy had an increased risk of developing an autism spectrum disorder.
U.S. health officials stress that the new ... Read More

A new study by researchers at Imperial College London has identified a way in which Salmonella bacteria, which cause gastroenteritis and typhoid fever, counteract the defence mechanisms of human cells.
One way in which our cells fight off infections is by engulfing the smaller bacterial cell... Read More

More than 1.6 billion years ago, one cell engulfed another and put it to work. More specifically, a eukaryotic cell, the sort of cell that contains distinct structures with different functions, took in a blue-green bacterium that could do something it could not: use sunlight to make sugars. The ... Read More
Scientists are closer to establishing a definitive bacterial cause for the skin condition rosacea. This will allow more targeted, effective treatments to be developed for sufferers, according to a review published in the Journal of Medical Microbiology.
Rosacea is a common dermatological cond... Read More
The pathogen Escherichia coli O157:H7 can spread, likely airborne, more than one tenth mile downwind from a cattle feedlot onto nearby produce, according to a paper published ahead of print in Applied and Environmental Microbiology. The high percentages of leafy greens contaminated with E. coli ... Read More
The human “microbiome”—the trillions of bacteria, yeasts, and other microscopic creatures that live inside a human body—has been one of the major science stories in recent years. It seems that barely a week goes by that we don’t learn something new about the relationship between the human body a... Read More
Amoebae — a group of amorphous, single-celled organisms that live in the human body — can kill human cells by biting off chunks of intestinal cells until they die, a new study finds. This is the first time scientists have seen this method of cell killing, and the new findings could one day help ... Read More
Researchers at The Ohio State University have discovered a new class of treatment against methicillin-resistant Staphylococcus aureus (MRSA) as well as evidence of a growing need to quickly genotype individual strains of the organism most commonly referred to as the "superbug."
The two separa... Read More
How much money would you need to put your health at risk? Ten thousand dollars? Five hundred? How about one single dollar? For a teenager in New York City, the latter was enough to test his fate in a subway station. In a video that has gone viral, a young unidentified teen was offered a dollar t... Read More
Thousands of German schoolchildren have fallen ill with a vomiting and diarrhea bug. Officials are still awaiting laboratory results, but the norovirus has been found in some cases.
